Study of nutritive value and antioxidant activity of Lactuca Runcinata and Portulaca Quadrifida

Plants are always used as medicines from long time and there is also a need for studying nutritive value and antioxidant activity of these plants. The present study includes various factors for experimental work and it involves plant extracts preparation from both fresh and dried materials as per methods used and showed significant result for both nutritive values like moisture content, mineral elements, proteins, carbohydrates, reducing and non-reducing sugars. The antioxidant activities of plants like Total Phenols, Vitamin A, Vitamin C and Free radical scavenging activity is considered in this study. There is always a need for an accurate determination of antioxidant capacity as it is gaining importance in most of the areas like food industry, therefore several analytical methods and measuring systems have been developed.
